Fantastic foresight from the player, certainly one for the record books. As far as my reseach goes, the fastest goal in English football is 4 seconds, Jim Fryatt (for Bradford Park Avenue v. Tranmere Rovers, 25 April 1964).
Nawaf Al Abed, the goalscorer, now sets the record at 2 seconds, for the fastest goal in football history. Unfortunately, upon review, the entire game was ruled invalid, as the team had six players over the age of 23 on the field in the second half. Not sure if he keeps his record, but for now, he will be credited with it.
This is why I love football!
